Well, I changed parameters, I removed the filter from web.xml file, I changed the bean... I know I've got to have a "multipart/form-data" form, a filter in web.xml file and a fileUploader to receive the event in the bean. However nothing is triggered. I click to choose and then to upload (if parameter is not auto="true") and nothing happens. I do have commons-io-2.4, commons-fileupload-1.3, primefaces-3.5 and I use GlassFish Server 4. Thank you!

I haven't tried GlassFish but found that using PrimeFaces 4 on WebLogic we had to add this parameter to the web.xml:

<context-param>
    <param-name>primefaces.UPLOADER</param-name>
    <param-value>commons</param-value>
</context-param>

We're using this Maven dependency:

<dependency>
   <groupId>commons-fileupload</groupId>
   <artifactId>commons-fileupload</artifactId>
   <version>1.3.1</version>
</dependency>

We also had to make sure that the PrimeFaces FileUpload Filter was the first filter entry in the web.xml. But it looks like yours is already.

Also, the file upload should have a form of its own.
